Multiple popup windows on same page? - popup

Question

I have a popup window that pops up when someone click on a button. The problem is that I want to have 6 buttons that will display different content but use the same style which doesn't work for me. Here is my current code (I found it on another post a few days ago):
JSFiddle: http://jsfiddle.net/j4c7U/
CSS:
#overlay {
display:none;
position:fixed;
left:0px;
top:0px;
width:100%;
height:100%;
background:#000;
opacity:0.5;
z-index:99999;
}
#popup {
display:none;
position:fixed;
left:50%;
top:50%;
width:300px;
height:150px;
margin-top:-75px;
margin-left:-150px;
background:#FFFFFF;
border:2px solid #000;
z-index:100000;
}
HTML:
<button id="LearnMoreBtn">Learn More</button>
<div id="overlay"></div>
<div id="popup">
Popup contents here
<button id="CloseBtn">ClosePopup</button>
</div>
<div>
some other content that will be behind the popup
</div>
Javascript:
window.onload = function() {
document.getElementById("LearnMoreBtn").onclick = function(){
var overlay = document.getElementById("overlay");
var popup = document.getElementById("popup");
overlay.style.display = "block";
popup.style.display = "block";
};
document.getElementById("CloseBtn").onclick = function(){
var overlay = document.getElementById("overlay");
var popup = document.getElementById("popup");
overlay.style.display = "none";
popup.style.display = "none";
}
};

I don't know if I completely understand the problem. Here is my JSFiddle with what I believe you're asking for.
Here is the resulting HTML:
<button id="LearnMoreBtn">Learn More</button>
<button id="LearnMoreBtn2">Learn More2</button>
<div id="overlay"></div>
<div id="popup">
Popup contents here
<button id="CloseBtn">ClosePopup</button>
</div>
<div id="popup2">
Popup2 contents here
<button id="CloseBtn2">ClosePopup</button>
</div>
<div>
some other content that will be behind the popup
</div>
